Zusammenfassung:FIELD: manufacture of building materials. SUBSTANCE: invention, in particular, relates to manufacturing in-door wall panels based on nonfired gypsum binder. Raw meal contains, wt %: nonfired gypsum binder 59-74, construction gypsum 3-6, lime water 13-15, and ground quartz sand (inert additive) 10-20. EFFECT: reduced solubility of gypsum semihydrate formed in gypsum dihydrate-quartz sand contact sites resulting in increased density and waterproofness of products. 1 tbl, 3 ex
